Hard enamel pins have become a popular choice for businesses, clubs, and collectors due to their smooth, polished finish and professional appearance. If you're considering creating custom hard enamel pins, understanding the manufacturing process, benefits, and how to select the right manufacturer is essential. This comprehensive guide covers everything from design to production, with insights into the materials, techniques, and options available when working with a hard enamel pin manufacturer.

What Are Hard Enamel Pins?

Hard enamel pins, also known as cloisonné pins, are high-quality lapel pins made by filling recessed areas of a metal base with colored enamel, then baking and polishing the surface to create a smooth, glossy finish. Unlike soft enamel pins, hard enamel pins have a flat surface with no texture, giving them a jewelry-grade look and feel. They are durable, long-lasting, and ideal for intricate or simple designs that require a professional finish.

The Hard Enamel Pin Manufacturing Process

Step 1: Design and Mold Making

The manufacturing process begins with a digital design submitted to the manufacturer. This design is used to create a steel mold through precision cutting and engraving. The mold undergoes heat treating to harden it, making it strong enough to withstand high-pressure stamping.

Step 2: Stamping and Shaping the Pin

Using the hardened mold, the design is stamped onto a metal plate-commonly iron or zinc alloy. The stamping machine applies around 5 tons of pressure to imprint the design. After stamping, a separate machine cuts out the pin's shape.

Step 3: Enamel Filling and Baking

The recessed areas of the stamped pin are filled with enamel colors. For hard enamel pins, multiple layers of enamel paint are applied and baked at high temperatures (around 1600°F) to harden the enamel. This process is repeated until the enamel is level with the metal edges.

Step 4: Polishing and Plating

Once the enamel is set and cooled, the pins are polished to achieve a smooth, glossy surface. The pins are then electroplated with metals such as gold, silver, or nickel to enhance their appearance and durability.

Step 5: Backing and Packaging

Finally, pin backings (such as butterfly clutches or rubber clutches) are attached, and the pins are packaged, often with options for custom backing cards or boxes.

Why Choose Hard Enamel Pins?

  • Smooth and Polished Finish: The enamel is flush with the metal, creating a sleek, professional look.

  • Durability: The hard enamel surface resists scratching and fading, making these pins ideal for long-term use.

  • High Perceived Value: Hard enamel pins are considered premium products, often used for corporate branding, awards, and collectibles.

  • Versatility: Suitable for both simple and detailed designs with up to eight colors or more.

  • Customization Options: Manufacturers often offer extras like laser engraving, glitter enamel, glow-in-the-dark effects, and custom back stamps.
